Temporal Changes In Mechanical Pin Prick Sensitivity Following High Frequency Induced Sensitisation Of Central Nociceptive Pathways: A Test Re-Test Reliability Study, Samuel Mugglestone, Giorgio Ganis, Sam W. Hughes

School of Psychology

High-frequency stimulation (HFS) is a human surrogate model of secondary hyperalgesia and a key experimental tool for understanding the mechanisms and modulation of central nociceptive pathways. An emerging area of research focuses on the role of top-down endogenous analgesic systems during secondary hyperalgesia development. However, the test-retest reliability of the early temporal changes in sensitivity are poorly understood. In the present study, we investigated the between-session reliability of the early temporal dynamics and late-phase expression of HFS-induced changes in mechanical pinprick sensitivity in a heterotopic area on the forearm in 28 healthy participants across five time points relative to HFS …

Sedentary Behaviors And Functional Disability Among Chinese Older Adults (2008–2018): Evidence Including Mahjong, Yen-Han Lee, Yen-Chang Chang, Minzhi Ye, Cai Xu

School of Social Work Faculty Publications

Purpose: This study examined how different types of sedentary behavior relate to changes in functional disability, measured by activities of daily living (ADL) and instrumental activities of daily living (IADL), among Chinese older adults.

Major findings: Using data from 17,939 participants in four waves (2008–2018) of the Chinese Longitudinal Healthy Longevity Survey (CLHLS), sedentary behavior was categorized into four types: none, playing mahjong only, combining these with other sedentary activities, and other activities alone (e.g., reading and watching TV). Cox two-state regression models estimated the hazard of transitioning in ADL and IADL disability. Engaging in sedentary behaviors was generally …

Impact Of Exercise On Mental Health In Inpatient Settings, Samuel Blake Rn, Nathaniel Clark Rn

Nurse Residency

In adult psychiatric inpatients with mental illness, how does participation in a structured exercise program compared with standard inpatient care affect depression, anxiety, and overall mental health outcomes during hospitalization?

The Impact Of Stigma On The Mmpi-3 Scores Of An Indo-Caribbean Community Sample, Julia Persaud-Naipaul

Theses and Dissertations

Evaluation of personality and psychological disorders is accomplished through the use of psychometric measures. However, tests require interpretation of test responses using a normative criterion based on a particular population that may not fully consider the effect of cultural influences on an individual’s level of willingness to report psychological difficulties. For example, individuals in collectivistic cultures may not be as willing to self-report problems because mental illness is often perceived as a source of embarrassment and shame. One culturally unique population that has been overlooked in psychological assessment is the Indo-Caribbean population. Their specific cultural values, beliefs, attitudes, and practices …

The Stickiness Of Meritocratic Beliefs From Adolescence To Adulthood In Singapore, Yen Kiat Chong, Shin Bin Tan, Vincent Chua, Han Ei Chew

Research Collection Office of Impact

The belief in meritocracy has been rising over the past few decades in developed countries. While many studies have focused on the belief in meritocracy, its distribution across groups and its effects, much less is known about how beliefs may change as individuals age and undergo major life transitions. Using linear growth models on three waves of panel data from a national youth survey in Singapore, we found that the major life transitions to adulthood – progressing through the education system (e.g., completing tertiary education), transiting from full-time studies to full-time work, getting married and becoming a parent – predicted …

Intracommunity Social Capital Systems Of Class And Caste In South Asian Intimate-Partner Violence Survivor Outcomes, Vriddhi Vinay

Dissertations, Theses, and Capstone Projects

This study theorizes how caste and class function as transnational forms of social capital that structure intimate partner violence (IPV) outcomes among South Asian diasporic women in the New York City metropolitan area. While existing IPV scholarship foregrounds migration status, gender, and legal precarity, it often treats South Asian communities as internally homogeneous and overlooks how intracommunity hierarchies mediate access to support. Drawing on social capital theory and postcolonial feminist frameworks, this research positions caste and class stratification as underexamined axes of stratification within United States-based IPV analysis. Using survey data from 24 South Asian woman-identifying IPV survivors in New …

Role Of The Corticostriatal Pathway In Learning With Interoceptive Nicotine Stimulus, Tyler Allen

Doctoral Dissertations

Tobacco use, primarily smoking, is the leading preventable cause of death, causing eight million deaths annually. Nicotine, the main addictive constituent of tobacco, acts as a reinforcer and as an interoceptive conditioned stimulus. While its pharmacology is well studied, the neural mechanisms of learning with nicotine remain underexplored. We examined the role of prelimbic cortex (PL) projections to the anterior dorsomedial caudate putamen (a-dmCPu) in nicotine-evoked goal-tracking. To achieve pathway-specific inhibition, we expressed Designer Receptors Exclusively Activated by Designer Drugs (DREADDs) in male and female rats. Subsequently, rats underwent self-administration conditioning in which active responses delivered intravenous (IV) nicotine followed …

Individual Differences In The Granularity, Complexity, And Diversity Of Bodily Sensations, Alexandra L. Ecker

Doctoral Dissertations

The majority of theories of emotion posit that the body is central to the experience of emotion (see, e.g., Barrett & Bar, 2009; Barrett, 2006; Lindquist, 2013; James, 1884; Schacter & Singer, 1962; Gendron & Feldman Barrett, 2009; Stemmler, 2004; Kreibig, 2010; Russell, 2003). Thus, it is no surprise that body awareness, or the subjective awareness of internal sensations (Mehling et al., 2009), has gained much attention in emotion research. There is some evidence that body awareness (BA) is related to both affective experience (i.e., general feelings of pleasantness/unpleasantness and activation/deactivation; MacVittie et al., 2025a), emotional intensity (i.e., the strength …

Parental Involvement In An Indonesian Islamic Kindergarten: An Instrumental Case Study Of Mothers’ Voices, Somariah Fitriani, Yessy Yanita Sari, Irdalisa Irdalisa, Hamidah Mohamad

The Qualitative Report

Parental involvement plays a critical role in children’s cognitive, effective, and psychomotor development; however, limited research has explored mothers’ perceptions of parenting and practices of parental involvement and parenting styles. This instrumental case study employed semi-structured interviews with 23 mothers in an Indonesian Islamic kindergarten to explore their understandings, experiences, and beliefs regarding parental involvement. It also aims to identify different kinds of parenting styles. The study revealed three themes, indicating that parenting and parental involvement are understood as an educating process, an interaction process between parents and children, and a mechanism for supporting children’s development. The findings indicate that …

Intimate Partner Violence And Emotion Regulation Among Emerging Adults: Investigating The Roles Of Dispositional Mindfulness And Executive Function In The Context Of A Laboratory-Induced Stress Paradigm, Mikell Bursky

Dissertations, Theses, and Capstone Projects

Intimate Partner Violence (IPV) is a major public health concern that impacts an estimated 10 million men and women in the United States annually. IPV refers to a range of physical, sexual or psychological forms of aggression committed against a current or former romantic partner in the context of a relationship. The highest rates of IPV are observed in emerging adulthood, a developmental period between the ages of 18 to 25 that is significant for the transition from adolescence into adulthood, and the establishment of first meaningful intimate relationships. Although distal risk factors for IPV such as violence in the …

Teaching Third Graders To Read Multisyllable Words: Segmentation Versus Whole Word Reading, Jolie D. Heath

Dissertations, Theses, and Capstone Projects

In the early years of elementary school when children are still learning to read, they are presented with words of increased syllable length, and orthographic and morphological complexity in the texts they read.  Although multisyllabic words comprise 90% of words in the English lexicon and carry important linguistic information for expanding vocabularies and comprehension of content, few studies have focused on teaching middle elementary children to read multisyllabic words.  Many children lack strategies to identify these longer more complex words accurately and easily, leading to reading difficulties that place weaker readers at higher risk for school related problems and limit …

Modeling And Generating Trustworthy Speech, Yuwen Yu

Dissertations, Theses, and Capstone Projects

As virtual agents become increasingly integrated into everyday communication, trust has become essential for effective human-AI interaction. Although recent advances in natural language generation and speech synthesis have significantly improved fluency and intelligibility, most systems are not designed to control how trustworthy they are perceived. As a result, a mismatch can emerge between perceived trustworthiness and actual system capability, leading to over-trust or under-trust. While trust is critical for meaningful interaction, current text-to-speech (TTS) systems are primarily optimized for naturalness and intelligibility rather than calibrated trustworthiness.

This dissertation investigates the perceptual foundations of trust in both human and synthesized speech …

New York City Women’S Experiences With Perinatal Depression Inquiries, Diagnosis, And Treatment Initiation, Caterina Pisciotta

Dissertations, Theses, and Capstone Projects

Perinatal depression represents a significant public health concern, yet many women who experience depression symptoms during the perinatal period (either during pregnancy and/or after birth) do not receive treatment. Initiatives, such as ThriveNYC, were designed to address these gaps by screening and treating perinatal women for maternal depression, integrating screening into routine perinatal care and strengthening pathways to treatment. Using representative survey data collected between 2016 and 2021 via the Center for Disease Control and Prevention’s Pregnancy Risk Assessment Monitoring System (PRAMS), this study examined trends in perinatal depression inquiries (a proxy for “screening”) and postpartum diagnosis, as well as …

Opportunities For Learning Through Object Exploration During Early Physical Therapy: Physical Therapists’ And Caregivers’ Assistance And Interference Behaviors, Michele Goncalves Maia

Dissertations, Theses, and Capstone Projects

Early physical therapy (EPT) for infants with motor delays has traditionally emphasized motor milestone acquisition, yet growing evidence indicates that motor and cognitive development are fundamentally interconnected. Grounded in embodied cognition and developmental cascade theories, this dissertation conceptualized object exploration as a primary mechanism through which infants learn during EPT and examined how intervention approaches and adult behaviors shape opportunities for object exploration. Using retrospective analyses of video-recorded EPT sessions, two studies investigated how intervention approaches and adult behaviors influence infants' opportunities to learn through object exploration. Study 1 compared object exploration in the START-Play (SP) intervention and Usual Care …

Gene-Environment Interactions In Cardiovascular Aging: Volunteering, Polygenic Risk, And Biomarker Change In European And African Ancestry Populations, Seoyoun Kim, Byeongju Ryu, Erin Ware, Koichiro Shiba, Cal J. Halvorsen

Brown School Faculty Publications

Volunteering has been associated with better cardiovascular health, but whether this association varies by genetic susceptibility to cardiovascular disease remains unclear. This study examined associations between volunteering and cardiovascular biomarkers, assessed associations between biomarker-specific polygenic scores (PGSs) and these outcomes, and tested whether polygenic risk moderated volunteering–biomarker associations among U.S. adults aged 51 years and older.

Neural Symphony Of Flow Experience: Evidence For High-Dimensional Metastable Dynamics, Abdelrahman B. M. Eldaly, Kris Zhangguang Kang, Fiona Fui-Hoon Nah, Leanne Lai-Hang Chan, Keng Siau, Xiao Fan Liu, Richard Huskey, Langtao Chen, Tejaswini Yelamanchili, Rene Weber

Research Collection School Of Computing and Information Systems

Flow, an optimal experience characterized by deep immersion and engagement in an activity, has been extensively studied in behavioral research. However, its neural dynamic mechanism remains poorly understood. In a within-subject video gaming experiment, we captured neural activity underlying flow, boredom, and anxiety using a 64-channel electroencephalogram (EEG) system. Compared to boredom and anxiety, flow exhibits the highest global functional connectivity, metastability, and dimensionality of dynamic functional connectivity patterns, suggesting that flow is a highly adaptable process that is supported by high-dimensional neural dynamics. Unlike previous studies that focused on identifying static or localized brain activity, we examine the neural …

Autonomy, Adolescents, And Artificial Intelligence, Michael J. S. Beauvais

Journal of Science & Technology Law

In this essay, I explore the potential implications of adolescent use of AI assistants on the development of adolescents’ capacities for autonomy. Thinking through these issues from the perspective of first principles is, I believe, needed in order to sharpen our understanding of some of the issues AI assistants pose for young people. A clear analysis will suggest which legal or policy prescriptions should follow.

I first give an overview of adolescent use of AI assistants, noting their popularity and the variety of use contexts. Drawing upon the work of Catriona Mackenzie, I then outline a relational conception of autonomy …

Comparing User Experiences Of Teleportation, Slide-Walk, And Walk-In-Place Locomotion Across Two Virtual Reality Games, Shane L. Rogers, Brett Ryder, Stephen Palmisano

Research outputs 2022 to 2026

Virtual reality (VR) locomotion methods differ substantially in their implications for usability, presence, and comfort. Although previous research has compared a range of locomotion techniques, relatively little attention has been given to whether locomotion experiences generalise across different VR experiences. The present study compared user experiences of three locomotion methods (teleportation, slide-walk, and walk-in-place) across two VR applications (Nature Treks VR, an exploration-focused environment, and Ancient Dungeon VR, an action-oriented game). Sixty-three participants were recruited, with analyses based on the forty-five participants who completed all study conditions. During each 10-min condition (comprising a 2-min familiarisation period followed by an 8-min …

Development And Psychometric Validation Of The Multidimensional Measure Of Purpose In Life Ii (Mmop-Ii), Louis Fang, Alfred Allan, Joanne M. Dickson

Research outputs 2022 to 2026

Purpose in life is a central motivational construct that has a profound influence on wellbeing. However, existing measures lack the breadth and precision needed to accurately capture this complex construct. In the present study, we aimed to develop a new measure rooted in a holistic, systems-based theoretical framework of purpose in life: the 18-item Multidimensional Measure of Purpose in Life II (MMOP-II). In Study 1, our confirmatory factor analyses in a sample of 303 university students (female = 82.5.%, white = 78.5%) supported a strong five-factor higher-order model fit, outperforming the three-factor and unidimensional alternatives. The Study 2 results replicated …
